The NRA has full time staffers who keep up with the gun laws around the country. This image shows in red the states that honor the Nevada permit. Every state has different laws regarding carry, so it's up to you to do the research on the state you plan to visit with your gun, and know their laws. Visit the NRA page where this came from and see the most current version, as it does change now and then. The find out more button will take you to the NRA's site.
You must visit the WCSO Info link under more info! It gives you instructions on how to make an appointment and apply for your permit. The system has changed, so you need to look!
